We can easily change the css class of an element using javascript. I am not sure that what do you mean by "change the css class of finction ".

You can change the css class of any element as

To replace all existing classes with one or more new classes, set the className attribute:

SQL

document.getElementById("MyElement").className = "MyClass";

To add an additional class to an element:

To add a class to an element, without removing/affecting existing values, append a space and the new classname, like so:

SQL

document.getElementById("MyElement").className += " MyClass";

Let me know if this resolves your problem

Solution 1

function ShowDescription(id,spanid) {
var elm = document.getElementById(spanid);
elm.removeAttribute("class");
elm.setAttribute("class","newClass");

}
